是否有扩展至当前选择器的预处理器宏？
这适用于 Objective-C，是否有预处理器宏或其他东西可以获取当前选择器的 SEL 值？具体来说，我正在寻找类似的东西：
-(void) someSelector
{
SEL mySelector = __CURRENT_SELECTOR__;
NSLog(@"I'm in selector %@",NSStringFromSelector(mySelector));
}
它有点像 __FILE__ 宏，但这是为了获取当前选择器。将其传递给其他人非常有用，同时不用担心在选择器名称更改时更新它。

This applies to Objective-C, is there a preprocessor macro or something to get the SEL value of the current selector? Specifically I'm looking for something like:
-(void) someSelector
{
SEL mySelector = __CURRENT_SELECTOR__;
NSLog(@"I'm in selector %@",NSStringFromSelector(mySelector));
}
it's kinda like the __FILE__ macro but this to obtain the current selector. Pretty useful to pass it to others while not worrying to update it if the selector name is changed.

每个方法都有两个隐式参数，
self，它是一个id（接收者）和一个名为_cmd的SEL，这可能就是你想要的。请注意，这与预处理器或编译时之前的任何内容无关，
_cmd不是宏，而是参数。Every method has two implicit parameters,
selfwhich is anid(the receiver) and aSELcalled_cmd, which is probably what you want.Note that this has nothing to do with preprocessor or anything before compile-time,
_cmdis not a macro, it's an argument.sidyl所说的应该可以回答你的问题。只是想添加，如果您只需要它进行日志记录，您也可以使用常用的 C 关键字，例如
What sidyll said should answer your question. Just wanted to add if you just need it for logging you can also use the usual C keywords, e.g.
_cmd 将为您提供当前选择器（仅在 Objective-C 中可用）
_cmd will get you the current selector(only available in objective-c)
